Growing interest to use natural preservatives and spices with antimicrobial effects and large amounts of floral bio-residues (92.6 g per 100 g) generated and wasted in the production of saffron spice guided this study  to evaluate  the opportunity to expand the uses of C. sativus flowers (petals and stamens), beyond the spice (dried stigmas). The antibacterial potential of total extrac...

The acidity constants of 4-(2-pyridylazo)resorcinol (PAR, Scheme 1) in binary mixtures of methanol–water at 25 ◦C and an ionic strength of 0.1 M have been determined spectrophotometrically. DATa ANalysis (DATAN) program applied for determination of acidity constants. As percent of methanol increases in solvent mixtures the pKa constants also increased. There is linear relationship between acidi...

Random copolymer gels of N-isopropylacrylamide (NIPAM) and N-ethylacrylamide (NEAM) were synthesized using a 1 : 1 monomer molar ratio in different methanol–water (xm 1⁄4 0, 0.06, 0.13, 0.21, 0.31 0.43, 0.57, 0.76, where xm 1⁄4 mole fraction of methanol) mixtures. The samples were characterized using different techniques like Fourier transform infrared spectroscopy (FTIR), scanning electron mic...

Oleo-gum-resin of Boswellia serrata Roxb. (Burseraceae) locally called ‘Kundur’, is one of the ingredients in certain Unani formulations used in renal diseases. In the present study, the effect of Kundur and its methanol soluble (MS), and methanol insoluble (MINS) fractions were investigated on Gentamicin induced nephrotoxicity in Albino rats. The renal effects of Kundur and its fractions were ...

BACKGROUND Asparagus gracilis subspecie of Asparagus capitatus Baker, is described as food and medicine for various ailments. In this study we investigated, its phenolic constituents, in vitro antioxidant potential against various free radicals and anti-urease potential. METHODS Asparagus gracilis aerial parts collected from District Islamabad, Pakistan were extracted with crude methanol whic...

This study examines the antimicrobial activity of the hexane, dichloromethane and methanol extracts of Lippia multiflora and carvacrol isolated from the hexane extract. The result shows the hexane extract to be the most active, while the methanol extract exhibited no antimicrobial activity. The isolated carvacrol from the hexane fraction showed tremendous antimicrobial activity. These results c...

Abstract Background Spondias mombin Linn. is a tropical climate plant with wide applications in ethnomedicinal practice. This study evaluates the phytotoxicity, cytotoxicity and chemical composition of plant’s stem bark. Methods Dried bark sample was subjected to exhaustive extraction partitioned into sub-fractions (hexane-ethylacetate, ethylacetate, ethylacetate-methanol methanol) by graded po...

Fractions prepared from the methanol extract of Buchholzia coriacea stem bark exhibited a high concentration-dependent antibacterial and antifungal activity compared to the standard antibiotics, ampicillin and tioconazole. In the brine shrimp lethality (BSL) assay, the methanol extract was found to be non-toxic with an LC(50) of 1031 microg/ml. The two main compounds present in the most active ...
